PRINTING APPARATUS.

Application filed January 3, 1916,.Seria1 No. 69,

To all whom it may concern:

Be it known that I, OVILA G. H'nBnR'r, a British subject, and residentof Holyoke, in the county of Hampden and State of Massachusetts, haveinvented certain new and useful Improvements in Printing Apparatus, ofwhich the following is a full, clear, and exact description.

This invention particularly relates toan improved holder for a line ofseparate type whereby the types, more or less in number, to constitutethe line may be firmly held, so that pluralities of the holders and typetherein may be confined in a carrier, having the nature of a chase, forprinting.

The type holder, moreover, comprises means whereby the types areautomatically centered therein.

The invention further relates to means whereby the type holders areuniformly centered relatively to the carrier or chase.

The invention is described in conjunction with the accompanying drawingsand is set forth in the claim.

In the drawings Figure l is a perspective View showing the presentimproved self centering type holder.-

Fig. 2 is a horizontal sectional view on line 2-2, Fig. 1.

Fig. 3 is a perspective view of the type holder carrier or chase,especially constructed and adapted with reference to the speciallyconstructed type holders to center the latter in such carrier.

The type holder A comprises an L-shaped bar having a longitudinal slotat in its back member I), which member rises at right angles from thebase member or ledge d which forms the bottom support for the type on.

B B represent a pair of clamping members slidable in the angular spacebordered by the back and base members of the L- shaped bar, inconjunction with which means are provided for imparting approaching andreceding movements simultaneously to both of such clamp blocks, so thatthe line of type, of whatever length the same may be, will be confinedcentrally of the holder.

The said clamp blocks are provided with tongues g 9 extended within thesaid slot a; and they are drilled and tapped with right and left handthreads.

D represents a right and left hand screw shaft rotatably mounted on butendwise Specification of Letters Patent. Patented Feb. 1Q, 1920 764.Renewed Jaly 21. 1919. Serial No. 312,436.

non-movable relatively to the back member of the bar,extended'lengthwise through said slot at, and having the reverselythreaded portions thereof engaging, each, the tongue 9 of one of theclamp blocks.

As shown, the plain or unthreaded end portions of the screw shaft D arefitted through alined bores or bearings h h in the portions 6 i of theback member I) of the holder bar, and are restrained against endwisemovements j and k,the one j being enlarged or in the form of a handleknob and peripherally milled or knurled to constitute a convenient meansfor the turning of the right and left threaded screw shaft.

The separate types, more or less in number, and to constitute a typeline of greater or less length, when placed on the L-shaped holder bar,between the sufficiently separated clamp blocks B B will, when suchclamp blocks are brought to approached and confining relationsrelatively to the types, automatically center the latter on the bar.

Each holder bar A is provided at the 'mid dle of its base or ledgemember d with a depending stud m.

This provision is made with reference to means especially provided inthe carrier or chase for one or a plurality of the type holders.

The carrier represented in Fig. 3 comprises a plate or body 0, a fixedend abutment 70, a clamping bar 9, and bar operating screw 73.

The carrier has in the body plate 0 thereof, centrally andlongitudinally, a groove or slot u.

The type holders A, to be confined between the clamping members 9 and p,and carried by the chase or device comprising such part, thereof engagedin the said groove to, whereby all of the type holders will be centeredin the carrier, and whereby all of the lines of type of a plurality ofthe type holders, centered in the latter, will be necessarily centeredin the carrier.

The printing devices above described, and shown, are especially usefulfor use in con junction with what in the trade is known as a benchembossing machine, in which types set up for brief titles or othermatter are used for the printing of cases comprised in the backs ofbooks, or for the printing of small sheets or strips of leather aclamping have the depending studs m' by the collars or shoulders orother material to be stuck on the backs of the book; but as manifest theinvention is susceptible of a Wider field of utilization.

I claim A type holder consisting of an L-shaped bar, a pair of clampblocks slidable in the angular space bordered by the back and basemembers of said bar, means for imparting approaching and recedingmovements simuL taneously to both of said clamp blocks, a carrier havingmeans for the confinement therein of type holders, provided With agroove in its base, and each type holder having a depending stud for acentering enga ement in such base groove of the carrier. igned by me atSpringfield, Mass, in presence of two subscribing Witnesses.
